DTC codes / C00xx · Brakes, steering and suspension / C006B
C006B indicates that the electronic stability control (ESC) system has been actively intervening for longer than the module considers normal, typically because a wheel speed sensor or steering angle sensor is reporting implausible data. The computer detects this when the stability control activation timer exceeds a calibrated threshold, often set between five and ten seconds of continuous or near-continuous intervention.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
